Diagnostic Specificity: While characteristic of MS, lesions near the anterior and temporal horns can also appear in migraine or stroke; however, lesions near the posterior horns and body of the lateral ventricles are highly specific to MS.

they are also called Dawon's fingers Dr. Dawson saw these in MS patients many many years ago I believe greater than 90 percent of patients dx with MS have these

Are you wondering what a periventricular lesion on the brain means in relation to MS? Great question — let's break it down in plain terms.

Are you wondering what a periventricular lesion on the brain means in relation to MS? Great question — let's break it down in plain terms.
In MS, lesions are areas of damage that form when the immune system mistakenly attacks the myelin sheath — the protective coating around nerve fibers. Periventricular simply means the lesions are located around the ventricles, which are fluid-filled spaces in the brain. These periventricular lesions are actually one of the most characteristic features of MS. They often appear perpendicular to the ventricles and around a structure called the corpus callosum. When they look like finger-like projections on an MRI, doctors call this pattern "Dawson's fingers" — which sounds a bit like a horror movie but is actually just a helpful diagnostic clue!
Depending on where exactly these lesions are located, they can cause a range of symptoms, such as:
- Memory or concentration difficulties
- Mood or behavior changes
- Speech difficulties
- Motor function changes
It's worth noting that not all lesions cause noticeable symptoms — some are "silent" but can still be tracked on MRI to monitor disease activity. Always discuss any new or changing lesions with your neurologist, as they can help interpret what the location and size mean for your specific situation and whether any adjustments to your treatment plan may be needed.
